CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 279,203, dated June 12, 1883.

- Application filed April 30, 1883. (N model.)

drawings.

This invention relates to corkscrews; and it has for its object to provide a simple, inexpensive, and efficient means for extracting the cork and also cutting the wire or cord generally used in securing the corks of bottles.

The said invention is an improvement upon that described in my application recently allowed, but not yet issued. I11 this allowed application I have described a corkscrew provided with a cutter having a sharp cuttingedge to sever the wire or cord; but in said case the cutter is secured to the shank, so that the extraction of the cork is effected by pulling onto the handle in the usual way.

My present improvement consists in providing the cutter with internal screw-threads, and arranging said cutter to work up and down in corresponding screw-threads on the exterior of the shank; and it also consists in the peculiar construction of the cutter, as will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 represents a perspective view of my corkscrew applied to the cork of a bottle, the parts be ing shown in the position of inserting the corkscrew. Fig. 2 represents a vertical section of the same, the parts being shown in the position preparatory to extracting the cork. Fig. 3 represents a similar view, the wire being shown as v severed and the cork extracted.

Like letters refer to corresponding parts in Referring to the drawings, A designates the handle, of any suitable shape and size, andhaving secured thereto the shank B and screw 0. As shown, the shank is screw-threaded its entire length, and a cutter, D, preferably coneshaped, has corresponding internal screwthreads at its upper end, which engage with the threads of the shank, and by the revolution of the handle said cutter moves vertically on said shank. The inner surface or interior of the cutter D is formed with a shoulder, (7 and then tapers gradually to the outer rim, 6.

In practice the cutter encircles the neck of the bottle, and the fiat under surface of rim 6 forms 5 5 a bearing for the corkscrew, while the inner edge, e, of the rim forms an inner cutting-edge to sever the wire and break the sealing-wax generally used in securing the corks of bottles. 1 The shoulder (Z also forms an inner cuttingedge to break the sealing-wax and sever the wire. This shoulder works well in case the corkscrew is used to extract the cork of a muchsmaller bottle, as the rim will then pass over the neck, and the fiat under surface of said shoulder bear upon the neck in the same manner as the rim.

In operation the screw is inserted into the cork in the usual manner, the position of the parts being as shown in Fi 1. By turning the handle the screw is forced down into the cork, and by the same operation of the handle the cutter moves down upon the neck of the bottle. The revolution of the sharp edge e of rim 6 againstthe cord or wire severs the same. After the cutter is down sufficient upon the neck of the bottle the handle is turned farther, and thus the screw is forced down into the cork, and the cork will then move upward upon the shank, as shown in Fig 3.

' By the use of my combined corkscrew and cutter I cut the wire or cord and extract the cork by the same operation. Heretofore the wire was obliged to be severed before the corkscrew was applied, thus necessitating consid- 8 5 erable loss of time. I combine these parts in one device, and make the same capable of performing the functions of each. In my corkscrew the cork is not damaged by its removal, and can be used over again.

My device is simple, durable, and inexpensive, and works with admirable efliciency, besides possessing other advantages too numerous to mention.
